       If called without an argument, this function rolls back the default
       transaction of the default link. If the argument is a connection
       identifier, the default transaction of the corresponding connection
       will be rolled back. If the argument is a transaction identifier, the
       corresponding transaction will be rolled back. The transaction context
       will be retained, so statements executed from within this transaction
       will not be invalidated.
